Hi.
Guys, I need your help. I have audio track in project. I try to pitch it in Melodyne. When I open Melodyne as extension (ARA2) I lost any sound from audio track. If I delete Melodyne extension sound returns back. At the same time, if I open audio track for VariAudio editing I hear sound from audio track. With other words, VariAudio doesn’t blocks sound, rather Melodyne blocks it. 
What I doing wrong? 
Melodyne version is 4.2.2.003
Cubase version 10.0.30
Nothing, it’s a bug in Cubae 10.0.30:
ARA 2 limitations in Cubase 10.0.30 and Nuendo 10.1
In Cubase 10, menu Studio → Studio setup → VST Audio System → Processing precision → set this to “32 bit float”.
Oh, I see.
Thank you very much for answer. You help me a lot!
This problem is not isolated to Cubase. I am using Logic Pro X and Melodyne ARA is muting the sound on only one of my audio tracks, which happens to be double bass. There doesn’t seem to be any rhyme or reason to it. The audio pitches that the bass part is playing are showing up in Melodyne, but the volume is turned off of that track for some reason. It’s not happening to my vocal tracks, my piano tracks, and a few other instrument audio tracks.
